Eating the world's hottest chilli pepper caused a young man in the US to suffer from excruciatingly painful 'thunderclap' headaches for several days, doctors including those of Indian origin have found.

According to a report published in the journal BMJ Case Reports, the patient's symptoms started immediately after eating a 'Carolina Reaper,' the world's hottest chilli pepper.

After an initial bout of dry heaves, he developed severe neck pain and crushingly painful headaches, each of which lasted just a few seconds, over the next several days, according to the doctors at Bassett Medical Center and Henry Ford Health System in the US.

His pain was so severe that he sought emergency care, and was tested for various neurological conditions, the results of which all came back negative.

According to the doctors, including Satish Kumar Boddhula, Sowmya Boddhula, and Kulothungan Gunasekaran, a CT (computed tomography) scan showed that several arteries in his brain had constricted, prompting them to diagnose him with thunderclap headache secondary to reversible cerebral vasoconstriction syndrome (RCVS).

RCVS is characterised by temporary artery narrowing often accompanied by thunderclap headache.

It does not always have an obvious cause, but can occur as a reaction to certain prescription medicines, or after taking illegal drugs.

This is the first case to be associated with eating chilli peppers, although they point out that eating cayenne pepper has been linked to sudden constriction of the coronary artery and heart attacks.

"Given the development of symptoms immediately after exposure to a known vasoactive substance, it is plausible that our patient had RCVS secondary to the Carolina Reaper," doctors said.

The man's symptoms cleared up by themselves. And a CT scan 5 weeks later showed that his affected arteries had returned to their normal width, they said.

Eyestrain Headaches - Here Are The Symptoms!

Eye Strain is an umbrella term that denotes a number of symptoms that relate to the extended use of eyes as well as discomfort that may come from excessive smartphone and computer use. This condition may or may not lead to significant eye damage and is usually characterised by blurry vision, headaches and a feeling of dryness in the eye as you blink less which creates less tears. This may happen due to the extended use of the eye when you are following objects on a screen or staring at a screen for too long. So, is eye strain the cause of your headaches?

Find out more in this article.

Causes: Eye Strain or Asthenopia is caused by concentrating on visually intense tasks like reading from texts that have a fine print, the use of computers and other screens for prolonged periods, and trying to focus on objects in the dark. This can lead to distress of the muscles in this area which can also cause eye strain leading to a variety of symptoms including double imagery and even headaches and mild migraine like conditions.

Eye Muscle Imbalance: When there is eye strain which leads to headaches, it can also give rise to eye muscle imbalance which makes it difficult to concentrate with both eyes at the same time. In such cases, one may need bifocal glasses so as to fix the issue and prevent such debilitating headaches to remain on a persistent basis.

Diagnosis: Digital eye fatigue and ocular eye strain leading to headaches can be diagnosed by a doctor with the help of regular eye examinations. In any case, one should have the eyes checked at least once a year. This is especially important if your job involves sitting in front of the computer screen for prolonged hours.

Symptoms: There are a variety of symptoms of these headaches that are caused by eye strain. Apart from blurry vision which does not allow the patient to see properly and clearly without glasses, it can also cause headaches with symptoms like nausea and sensitivity to light. Retinal or eye migraines do not necessarily have to come with headaches, but the pressure can be painful enough.

Treatment: To begin with, the best form of treatment for headaches born from eye strain includes prevention which can be done by getting plenty of rest and sleep even as we limit the hours spent in front of the screen. One can also lower the resolution of the screen and make it more ambient. Also, the screen should be placed at a considerable distance from the eyes. The doctor can also prescribe glasses and eye drops for better eye lubrication.

How to get rid of migraines and headaches

HEADACHES CAN BE triggered by any number of factors, including lack of sleep or food, anxiety, or even medications.

But when the pain in your head won't go away, try these remedies, specific to the type you're experiencing.

1. Tension Headache
Symptoms: Pain on both sides of your head. These are the most common type—affecting 70 percent of men—and are usually triggered by extreme stress or neck strain.

Treatment: Over-the-counter drugs are usually all that's needed (aspirin, ibuprofen, acetaminophen). But you may also find relief with a massage to loosen tight neck muscles.

Prevention: Sit up straight at work. Sitting hunched over your desk all day can set it off, especially if you're under stress. Keeping tension headaches at bay may be as simple as a quick walk outside away from the tumult of the office.

2. Migraine
Symptoms: Intense, throbbing pain, usually on one side of your head, accompanied by nausea and/or sensitivity to light or sound. Not fun. It's uncommon for men in their 20s or over to start developing migraines, so if you've never had one before, that pain is probably something different.

Treatment: Prescription meds such as sumatriptan are most helpful. So is rest in a quiet, dark room.

Prevention: Identify and eliminate your triggers (the most common are red wine, cheese, and caffeine). Regular exercise has also been shown to reduce frequency and severity.

3. Cluster Headache
Symptoms: A sharp pain behind one eye that strikes suddenly, and goes away just as quickly. The headaches come in groups — or clusters — and can reoccur for days or months. Cluster headaches are rare, affecting less than 1% of adult, but men in their 20s are more likely to get them.

Treatment: Oxygen therapy has been shown to help alleviate the pain. You also may want to get checked for sleep apnea — up to 80% of cluster headache sufferers also have the condition, and treating one may help eliminate the other.

Prevention: They are hard to predict, but there are several drugs, including Sansert (methysergide maleate), that your doc may recommend as a preventive measure.
